Letters Patent No. 93,956, dated August 24,1869.

The Schedule referred to in these Letters Patent and making pari.' ofthesame.

Teo all whom fit may concern:

'Be it known that I, SAMUEL BRADBURY, of Dres,

den, in the county of Petts, and State 'of Missouri, have invented a newand useful Improvement in Cornbined Roller, Harrow, and Drill; and I dohereby declare that the following is a full, clear, and exactdescription 1 the seat and part of the halrow-teeth being removed.

Figure 2 is a Side view of the Same.

Figure 3 is a detail view of the detachable collar.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an imiproved'combined barrow,roller, and drill, which shall be so constructed and arranged that theroller maybe used alone, or the roller and harrow, or the roller and,

drill, or the roller, harrow, and drill, as the circum` stances of thecase may render advisable, doing its work well in either capacity; and

It consists in the Vconstruction and combination of the various parts ofthe machine, as hereinafter more fully described.

A is the frame of the machine, to the forward part of which the tongue Bis attached, and to. the under side of the-middle parts of the side-barsof which,

are'attached brackets or standards C, in bearings in the lower ends ofwhich the axlejl), of the rollerE F, revolves, so that the said framemay ride upon and be supported by the said axle of the said rollers.

The roller is made in two parts, E F, the part/E of which, is securelyattached to the axle D, so as to carry the said axle withit in itsrevolution.

The part F, of the roller, revolves loosely upon the axle D, in such away that it may be moved longitudinally upon said axle.

The roller E F is made about ten inches shorter.

1 than the space between the Side-'timbers of the frame A, so that whenthe machine is used for harrowing or drilling, the part F, of theroller, may be moved close up to the part E, and so that when themachine is used for cultivating corn, the parts of the roller may bemoved apart, as shown in iig. 1, to allow the row of plants to passbetween the parts of the roller.

The part F, of the roller, is kept in either position by the open collarG, which is dropped upon the axle l1 at one or the other end of the partF, and which is. made with a handle, g', of vsuch a length als to restagainst a cross-bar of the frame A, and thus prevent the said opencollar from dropping orworking off the axle D.

The handle g is also convenient for attaching and detaching the collarwhen required.

H are the harrow-teeth, which are made with a curve so as. to stir theground with a lifting movement.

The upper ends of the teeth H are pivoted to the rear ends of thebeamsor draught-bars I, and are kept from being forced too far back byshouldersY or heads, h', formed upon their upper en'ds.

The forward parts of the draught-bars orbeams I are branched, f as shownin fig. 1, and their forward ends are pivoted to a cross-rod, J,attached to the forward part kof the frame A.

The draught-bars or beams are made longerand shorter, alternately,asshown in gs. 1 and 2, so that the barrow-teeth may be arranged in tworows.

K are chains, the lower ends of' which are attached to the upper partsof the teeth H, and the upper ends of which are attached to the rollersL,\the chains from `the forward teeth being connected with the forwardroller, and the chains of the rear teeth being connected lwith the rearroller. The journals of the rollers L work in bearings attached to theframe A, aud t0 each of said rollers L,

is attached a lever, M, by means of which the rollers L may be turned towind up the chains K, and thus raise the teeth H away from the ground.

The leversM, when moved into position to raise the teeth H away from theground, are caught and held by catches, Nattached to the iiame A, ortongueA B, so 'as to hold the said barrow-teeth away from the ground aslong as may be required.

0 is a seed-box or hopper, attached to the rear part Vof the frame A,andA from which the seed is conveyed to the conductor-spouts, (not shownin the drawings,) by which it is conducted to the hollow or tubularStandards, P, by the dropping-cylinder Q, which revolves in bearings inthe ends ofthe box O,and which is driven by the chain or band R, whichpasses around a pulley,

S, attachedto the end of the roller-shaft D, and around' a pulley,.T,attached to the end of -the droppingicylinderl Q.

Upon the lower ends of. the tubular standards P,

are fprmed, or to them are attached points U, to open. the ground toreceive the seed. The draught-strain'upon the standards P, is Sustainedby the draught-bars or beams V, to the rear ends of which the upper endsof thesaid standards P are securely attached.

The forward parts of the' draught-bars or beams V,

are branched, and their forward ends are pivoted to a.

cross-bar of the frame A.

W are chains, the lower ends of which are attached to the upper parts ofthe tubular standardsv IE', or to the rear ends of the draught-bars V,and their upper endsare attached to the roller-X, which revolves inbearings attached to the rear part of the frame A.

Tonne end of the roller X is attached a crank, Y,

to the crank-pui of which is pivoted the rear end of the connecting-barZ, the forward end of which is pivoted to the lever A.

The lower end of the lever Ais pivoted to the frame A, and its upper endextends up into such a position that it may be conveniently reached andoperated by the driverfrom his seat, to raise the tubular standards Paway from the ground when desired.

B is a catch, attached to the frame Ain such a position 'as to take holdof the lever A', when moved into by Letters 2. The combination of thechains K, rollers L, levers M, and catches N, with the barrow H I andframe A, substantially as herein shown and described,'and

'for the purpose set forth.

3. The combination Aof the barrow HI, rollers E F, and drilling-device Ok1?' V, with each other, and with the iame A, substantially as hereinshown and described, and for the purposes set forth.

4. The adjustable roller D E F, constructed and operating substantiallyas herein shown and described, and for the purpose set forth.

5. The combination of the chains'W, rollers- X,A crank Y, connecting-rodZ, lever A', and catch B', with the drilling-standards T, draught-barsV, and frame A, substantially in th manner herein shown and described,and for the purpose set forth. SAMUEL BRADBURY. Witnesses:
